By Matt Spetalnick WASHINGTON (Reuters) – U.S. investigators are looking at a range of theories, including the possibility of a “viral” attack, to explain what may have sickened some American diplomats who were stationed in Havana, the State Department said on Tuesday. U.S. experts have yet to determine who or what was behind the mysterious illnesses that began occurring in late 2016 and heightened tensions between the old Cold War foes. State Department officials testified that it was “incomprehensible” Cuba’s Communist government would not have been aware of what happened or who was responsible, though they stopped short of assigning direct blame to Havana.

The United States may again close its embassy in Cuba, which reopened two years ago after a half-century stand-off, following a series of mystery “health attacks” on its diplomats, Secretary of State Rex Tillerson said Sunday. At least 21 members of the US mission in Havana and a smaller number of Canadians have suffered brain injuries and hearing loss in what have been reported as “acoustic attacks”, although US officials say their origin remains unclear. The incidents began last year, and the latest was recorded in August, despite US authorities having complained to Cuban officials in February and having expelled two Cuban diplomats from Washington in May.

Cuba emerged from a 72-hour thrashing by Hurricane Irma on Monday with three-quarters of the population without power, as the country began the task of restoring basic infrastructure and services. Among the worst-hit areas were Havana, where at least seven bodies were recovered, and the coastal towns of Caibarien and Cojimar. Dazed citizens like Yanmara Suarez surveyed the devastation in the historic old town of Havana, largely submerged by a wind-whipped tidal surge that left many people wading in waist-high water over the weekend.
